>>> import validators
>>> validators.between(0, min_val=0, max_val=5)
ValidationError(func=between, args={'value': 0, 'min_val': 0, 'max_val': 5})
>>> validators.between(1, min_val=0, max_val=5)
True
>>> validators.between(0, min_val=-1, max_val=5)
ValidationError(func=between, args={'value': 0, 'min_val': -1, 'max_val': 5})
>>> validators.between(-1, min_val=-1, max_val=5)
True

For now I downgraded to validators to 0.11.0, which seems to be an old/different version of the module to work around this issue.
